Hi. Welcome to OIZOM Academy. Lets begin with All you need to know about PM1. Particulate Matter is not a single air pollutant, but refers to a complex mixture of solids and aerosols of varying shape, size, and chemical composition. They are composed of various chemical species like organic compounds, inorganic ions, metallic compounds, elementary carbon, etc. As the impact of particulate matter exposure on human health directly depends on the size of the particles, they are classified by their diameter for air quality regulatory purposes. The particles with a diameter of 100 μm or less are collectively known as PM100. Examples include wood particles, dust, etc. PM100 are directly emitted from sources such as such as wind-blown dust from open land, pollen, spores, mold, dirt, soil erosion, and forest fires, Burning fossil fuels, dust emission from unpaved roads, crushing and grinding, or other such uncontrolled construction activities, etc PM100 can enter the nose or mouth while breathing and get deposited in the air passages of the body. They may cause adverse health effects such as by allergic reactions, heart diseases, silicosis, etc Short term exposure to PM100 can aggravate already present respiratory diseases such as asthma while long term exposure can affect respiratory mortality. . PM100 in the atmosphere causes visible air pollution affecting the aesthetics of the surrounding environment. PM100 monitoring is an efficient way to detect high concentrations of particulate matter and prevent high-level exposures. Different working principles for monitoring particulate matter of all sizes in the ambient environment are Gravimetric, TOEM, Beta Attenuation, and Laser scattering. Oizom’ PM sensor works on the Active Sampling method of laser scattering that counts particulate matter using a highly accurate laser beam. Oizom’s Dustroid is an online particulate monitoring system that measures the concentration of various particulate sizes ranging from 1 micron to 100 microns such as PM1, PM2.5, PM10, and PM100 in the ambient air. Dustroid can be used for dust monitoring in areas with dust-laden activities like construction, mining, quarrying, ports, metallurgical processes, and many more. Real-time particulate matter monitoring using Dustroid can assist in dust suppression automation, for instance, to activate suppressants at the location once the threshold is breached. I hope you now know all about PM100. For any questions or suggestions, please contact us. Thank you and Happy Learning!

All you need to know about Dust Monitoring PM100
PM100 are complex mixture of solid and aerosols with
diameter of 100 μm or less composed various
chemical species like organic compounds, inorganic
ios, metallic compounds, elementary carbon, etc.
They are also known as “inhalable dust” as this
fraction of the particulate matter can enter the nose
and/or mouth while breathing and gets deposited in
the air passages between the mouth, the nose, and
the larynx. Examples include wood particles, dust, etc.

All you need to know about Dust Monitoring PM100SOURCES
Natural sources: wind-blown dust from open land, dirt, soil erosion, etc.
Anthropogenic Sources:
● Crushing, grinding, splitting activities
● Dust emitted from unpaved and paved roads
● Uncontrolled construction activities
● Dust and dust from factories, agriculture, landfills
● Emission from industrial processes
● Metal and steel production as well as the reloading of bulk material

All you need to know about Dust Monitoring PM100ADVERSE IMPACTS
HEALTH IMPACTS OF PM100
● PM100 generally enter the nose and throat when
inhaled and may cause adverse health effects such as
by allergic reactions, heart diseases, silicosis, etc
● Short term exposure to PM100 aggravates already
present respiratory diseases such as asthma while
long term exposure can affect respiratory mortality.
● Some of the inhaled particulate matter are toxic and
can imply additional risks because of their hazardous
properties such as nasal cancer, pulmonary fibrosis,
etc.

All you need to know about Dust Monitoring PM100ADVERSE IMPACTS
ENVIRONMENTAL IMPACTS OF PM100
● High levels of PM100 causes visible air pollution
affecting the aesthetics of the surrounding
environment.
● Settling of PM on plant, soil and water
ecosystems have negative impact.
● The metal and organic compounds reduce plant
growth and yield while the deposition of PM
into water bodies affects its quality and clarity.

All you need to know about Dust Monitoring PM100CORRECTIVE MEASURES
The primary action is dust monitoring to identify the areas with high particulate
levels In addition to this, the following corrective measures can be taken:
● Limit outdoor activities and close windows and vents during times of high air
pollution.
● Avoid areas with traffic congestions, construction activities, or unpaved roads.
Breathing such polluted air daily also leads to health effects in the long run.
● Eliminate the use of the fireplace, wood stove, gas-powered lawn, or garden
equipment.
● Eliminate open burning of leaves, trash or other materials.

All you need to know about Dust Monitoring PM100MONITORING METHODS
High-volume Gravimetric Method
The dust monitors based on the gravimetric principle
takes in the ambient air for 24 hours at a constant flow
rate through a size-selective inlet that only allows
particulate matter with an aerodynamic diameter of 100
µm or less to pass through.
Dust present in the ambient air is collected on a pre
weighted and pre-conditioned filter which is weighted
again after 24-hours to determine the mass of PM
collected which is proportional to the PM concentration.

All you need to know about Dust Monitoring PM100MONITORING METHODS
Beta Attenuation Monitor (BAM)
The dust monitoring based on the BAM principle
measures the particle mass density using beta radiation
attenuation.
The particulates in the ambient air drawn into the dust
monitor are deposited on a paper-band filter and
exposed to beta rays (i.e. electrons with energies in the
0.01 to 0.1 MeV range) which get attenuated as a function
of the particulate mass. The beta count reduces with an
increase in the PM mass and is recorded by the detector
and converted to concentration.

Laser Scattering
The dust monitor based on the physical principle of
light scattering, also known as optical particle counter
(OPC), measures dust particles illuminated by laser
light at a 90° angle.
The light scattered from each particle is collected at
approximately 90° by a mirror and detected by a
photodiode and fed into a multi-channel size classifier
where a pulse height analyzer is used to classify the
pulse that is proportional to the particle size. The
counts in the PM channel are converted to
concentration.
